I just started taking Tri-Sprintec about a week ago. I was on Gianvi(genaric for Yaz) for about 6 months. I was fine on that. But starting Tri-Sprintec i feel sick every time i take it at night and sometimes when i wake up in the morning. I know I'm not pregnant because I haven't had sex in over 6 months. I'm not 100% sure if I'm having a reaction to Tri-Sprintec or if its just my body getting used to it. Help??
